Hyperacusis - Wikipedia, the free encyclopedia Hyperacusis is a health condition characterized by an over-sensitivity to all or certain frequencies of sound (a collapsed tolerance to normal environmental sound). Although severe hyperacusis is rare, 40% of tinnitus patients complain of mild hyperacusis. Hyperacusis is also common in advanced Lyme disease due to nerve inflammation and the neurotoxic nature of the spirochetal bacteria. en.wikipedia.org /wiki/Hyperacusis   (353 words)

Fact Sheet: Hyperacusis ? An increased sensitivity to everyday sounds Hyperacusis is a condition that arises from a problem in the way the brain’s central auditory processing center perceives noise. Those suffering from hyperacusis may be uncomfortable with placing sound directly in their ear, but the device produces a gentle static-like sound (white noise) that is barely audible. Hyperacusis is strongly associated with tinnitus, a condition commonly referred to as “ringing in the ears.” Nearly 36 million Americans suffer from tinnitus; an estimated one of every thousand also has hyperacusis. www.entnet.org /healthinfo/hearing/Hyperacusis.cfm   (636 words)

hyperacusis Hyperacusis is defined as a reduced tolerance to normal environmental sounds and everyday sounds are unbearably or painfully loud (increased sensitivity to sound). The most suspect of Hyperacusis cause is damage to the cochlea (he cochlea is a coiled, tapered tube inside the inner ear, responsible for transmitting sound to the sensory organ of hearing) due to exposure to loud noises such as: Hyperacusis patients find that their condition is worsened not only when they are exposed to noise, but also when they go too far to protect their ears from it. www.sinuswars.com /tinnitus/hyperacusis.asp   (537 words)

Deafness Research UK : Hyperacusis : Hyperacusis   (Site not responding. Last check: 2007-11-03) Hyperacusis is the medical term used to describe abnormal discomfort caused by sounds that are tolerable to listeners with normal hearing. Hyperacusis may follow a blow to the head or exposure to loud noise but, for many people, the onset is sudden and inexplicable. Hyperacusis may describe the sensation caused by particular sounds as 'painful', 'startling' or 'anxiety producing' but it is still not clear why individual sufferers are disturbed by some sounds while other, often louder sounds, do not cause problems. www.deafnessresearch.org.uk /?lid=1630   (648 words)

Hyperacusis: Evaluation, Diagnosis, and Treatment. - Treatment & Research Unilateral or bilateral hyperacusis or deafness in patients with normal sound audiometry is often attributed to demyelinating lesions in the central auditory pathway. A separate aetiology of central hyperacusis is therefore proposed, with a symptom profile distinct from the peripheral hyperacusis. Hyperacusis, and the combination of both hyperacusis and tinnitus, were found to be significantly more frequent among women than among men. www.hyperacusis.org /wst_page5.html   (1218 words)

H.E.A.R. | Are You At Risk? | Hearing Education and Awareness for Rockers Hyperacusis is an unusual sensitivity to sound that is a symptom of several disorders including Meniere's disease and tinnitus. Hyperacusis should not be confused with the better known problem of "recruitment" which bothers many people who are hard of hearing. New evidence indicates that hyperacusis, as well as other kinds of oversensitivity, such as intolerance of light, may be linked to a deficiency of a specific chemical in the brain responsible for controlling the amount of information being transmitted from the senses. www.hearnet.com /at_risk/risk_tinnitus.shtml   (611 words)

Hyperacusis Some people with hyperacusis have such a severe intolerance to sound, that it is difficult and sometimes impossible for them to function in our everyday environment with all its ambient noise. All sounds may be perceived as too loud, although for most patients with hyperacusis, the high frequencies are particularly troublesome. Because of this, hyperacusis patients may feel as though, in addition to having less tolerance to sound, they can hear even better than those with normal ears. healthlink.mcw.edu /article/990316608.html   (436 words)

Hyperacusis Hyperacusis is abnormal sensitivity to everyday sound levels or noises, often there is sensitivity to high pitched sounds. Hyperacusis on its own affects only 1 in 50,000 people, but is present in 1 in 1,000 people who have tinnitus. People with hyperacusis sometimes can have a very low threshold to sound and it may be difficult and sometimes impossible for them to remain in the mainstream of life (socially unfit). www.medindia.net /Patients/PatientInfo/hyperacusis.htm   (733 words)

Hyperacusis   (Site not responding. Last check: 2007-11-03) Hyperacusis is used to describe a high level of sensitivity to sound.

ESG: Hyperacusis   (Site not responding. Last check: 2007-11-03) Hyperacusis is a fairly rare disorder defined as a reduced tolerance to normal environmental sounds. Individuals with hyperacusis may not have any hearing loss, while individuals with recruitment have sensorineural hearing loss that is characterized by reduced thresholds on an audiogram. For individuals suffering from severe hyperacusis, the most difficult challenge is functioning within a family and among a general medical community that do not understand the everyday obstacles posed by the disorder. www.earspecialtygroup.com /esghyper1.html   (658 words)

[No title] Ninety percent of hyperacusis victims also have tinnitus (ringing in the ears) and each exposure to a loud noise makes the condition worse--necessitating constant protection of the ears, meaning a secluded life, often on disability, as victims can't tolerate noise in the workplace. There are other, related disorders, hyperacute hearing, which is almost identical to hyperacusis, except the victim is born with it and it usually accompanies autism, and recruitment, a more common type of sound sensitivity that usually strikes the elderly. Hyperacusis is also an otological complication of herpes zoster and craniomandibular disorders. www.menieres.org /jacki/jackis66.htm   (1165 words)

American Tinnitus Association | About Tinnitus | Consumer | Other Hearing Disorders   (Site not responding. Last check: 2007-11-03) Hyperacusis is an abnormal intolerance to ordinary sounds. Although the exact point of injury and the mechanism responsible for hyperacusis are not definitively known, most researchers believe that hyperacusis ultimately is the result of a dysfunction in the brain’s sound regulatory mechanism. Many hyperacusis and tinnitus patients who use TRT find that the symptom of hyperacusis improves more quickly than the tinnitus –; usually within six months. www.ata.org /about_tinnitus/consumer/other_disorders1.html   (1136 words)

Hyperacusis: When Hearing Hurst - Tinnitus Information Center In a survey conducted by the American Tinnitus Association, of 112 patients with both tinnitus and hyperacusis, 53% reported their hyperacusis was worse than the tinnitus, 25% reported both problems as equally disturbing and only 16% who said the tinnitus was the most bothersome problem. The exact genesis of hyperacusis is unknown but there are studies that point to the part of the auditory system that regulates instructions from the central nervous system. The aim of the therapy is to retrain the patient’s brain so they learn how to treat tinnitus and hyperacusis the way they treat the sound of the refrigerator in their kitchen; a sound which they normally are not aware of but when they do hear it, it is not bothersome. www.tinnitusformula.com /infocenter/articles/conditions/hyper.aspx   (1158 words)

Hyperacusis People with reactive depression, however, a condition not infrequently seen in tinnitus and hyperacusis, seem to respond as well as anyone else - especially when the depression is addressed by a therapist willing to work with the TRT clinician. This phenomenon, which is observed more with tinnitus than with hyperacusis, is felt to be unrelated to possible malingering or potential secondary gain. Rather it has to do with the seemingly endless flow of paperwork and monthly justification required by the legal/insurance industry in such cases, paperwork (not to mention interviews) which by its nature causes something we wish to be less of an issue (tinnitus/hyperacusis)... pages.prodigy.net /unohu/hypera.htm   (1945 words)

New Page 1 Hyperacusis is due to an alteration in the central processing of sound in the auditory pathways where there is an abnormally strong reaction from exposure to moderate sound levels. Since all people with hyperacusis can be helped by a behavioural approach with 'sound' therapy, it has become clear that the symptoms cannot be the result of irreversible ear damage. This is particularly true in hyperacusis, where on some occasions, particularly in young children, it is all the treatment required. www.tinnitus.org /home/frame/hyp1.htm   (2471 words)

Hyperacusis: Evaluation, Diagnosis, and Treatment. People with hyperacusis may find that certain sounds are more difficult to listen to than others, and some sounds may cause pain in the ears, even when those sounds don't bother others. Sometimes, hyperacusis can be so severe that people begin to avoid any public or social setting in a vain attempt to protect their ears from any sounds. In the case of hyperacusis, detecting which of these billions of electrical or biochemical processes has changed is still impossible. www.hyperacusis.org   (477 words)

Terms such as 'oversensitive hearing,' 'hyperacusis,' 'phonophobia,' 'recruitment,' 'dysacusis,' and 'auditory hyperesthesia,' were used interchangeably (and incorrectly) to describe decreased sound tolerance, and discomfort or pain in the ears, associated with sound exposure. Moreover, serotonin was indicated as involved in hyperacusis, and a recent case report indicated that serotonin reuptake inhibitors might be helpful for hyperacusis. Decreased sound tolerance, including hyperacusis, misophonia, and phonophobia, is a challenging topic to study and a challenging symptom to treat. www.audiologyonline.com /articles/article_detail.asp?article_id=291   (1654 words)
